Standard Model Theory for the FCC-ee Tera-Z stage
A. Blondel, J. Gluza, S. Jadach +35
The future 100-km circular collider FCC at CERN is planned to operate in one of its modes as an electron-positron FCC-ee machine. We give an overview comparing the theoretical stat…
Double bremsstrahlung from high-energy electron in the atomic field
P. A. Krachkov, R. N. Lee, A. I. Milstein
The differential cross section of double bremsstrahlung from high-energy electron in the electric field of heavy atoms is derived. The results are obtained with the exact account o…
High-energy photoproduction in the field of a heavy atom accompanied by bremsstrahlung
P. A. Krachkov, R. N. Lee, A. I. Milstein
Helicity amplitudes and differential cross section of high-energy photoproduction accompanied by bremsstrahlung in the electric field of a heavy atom are derived. The resu…

R. N. Lee, A. I. Milstein, I. S. Terekhov
A quantum mechanical model of two interacting electrons in graphene is considered. We concentrate on the case of zero total momentum of the pair. We show that the dynamics of the s…

R. N. Lee, A. I. Milstein, V. M. Strakhovenko
First quasiclassical correction to the differential cross section of high-energy electron-positron photoproduction in the electric field of a heavy atom is obtained with the exact…
Application of the DRA method to the calculation of the four-loop QED-type tadpoles
R. N. Lee, I. S. Terekhov
We apply the DRA method to the calculation of the four-loop `QED-type' tadpoles. For arbitrary space-time dimensionality D the results have the form of multiple convergent sums. We…
Differential equations and high-energy expansion of two--loop diagrams in D dimensions
A. V. Bogdan, R. N. Lee
New method of calculation of master integrals using differential equations and asymptotical expansion is presented. This method leads to the results exact in space-time dimension $…

R. N. Lee, A. I. Milstein, V. M. Strakhovenko +1
The differential and partially integrated cross sections are considered for bremsstrahlung from high-energy electrons in atomic field with the exact account of this field. The cons…
Electric polarizabilities of proton and neutron and the relativistic center-of-mass coordinate
R. N. Lee, A. I. Milstein, M. Schumacher
We argue that the relativistic correction to the center-of-mass vector can lead to the approximate equality of the proton and neutron electric polarizabilities in…
Photon splitting in atomic fields
R. N. Lee, A. L. Maslennikov, A. I. Milstein +2
Photon splitting due to vacuum polarization in the electric field of an atom is considered. We survey different theoretical approaches to the description of this nonlinear QED proc…
Structure of the Coulomb and unitarity corrections to the cross section of pair production in ultra-relativistic nuclear collisions
R. N. Lee, A. I. Milstein, V. G. Serbo
We analyze the structure of the Coulomb and unitarity corrections to the single pair production as well as the cross section for the multiple pair production. In the external field…

The quasiclassical Green functions of the Dirac and Klein-Gordon equations in the external electric field are obtained with the first correction taken into account. The relevant po…

A simple integral representation is derived for the quasiclassical Green function of the Dirac equation in an arbitrary spherically-symmetric decreasing external field. The conside…
